Application filed April 30, 1914.

To all 107mm t may concern Be it known that l, ERNEST Gr. DUs'riN, citizen of the United States, residing at Kewvanee, in the county of Henry and State of Illinois, have invented certain new and useful improvements in Fasteners, of which the following is a specification.

My invention relates to new and useful improvements in fastening devices, and has as its principal object to provide a fastener consisting essentially in a body plate and a rotatable catch member which is equipped with a spring adapted to hold it in either open or locking relation to the structure to which the fastener is applied.

A. further object is to construct the fastenerl with suoli regard to proportion, number and arrangement of parts that it may be cheaply manufactured, will be durable and eiiicient in its action and may be employed in connection with a number of different structures for holding any movable member thereof in closed position.

The above and additional objects are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification, and then more particularly pointed out in the claims, which are appended hereto and form a part of this application.

lilith reference to the drawings, wherein there has been illustrated the preferred embodiment of this invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts, Figure 1 is a front elevation of a door, showing the fastener employed in holding a screen section thereof in closed position; Fig. 2 is a longitudinal section taken through a fountain brush and showing the fastener in position for normally holding thebrush in position in the casing of the brush; and Fig. 3 is a composite view illustrating perspectively and in detail the various elements of the fastener in disassembled relation, but indicating the manner in which they are adapted to be assembled to constitute an operative fastener.

Before taking up the detailed description of the drawings, l desire to emphasize the fact that while l have designed my fastener particularly for use in connection with fountain brushes of the type shown in Fig. 2, or screen doors, as shown in Fig. 1, it is, nevertheless, adapted for use on almost any type Specication of Letters Patent.

of structure wherein it is desired at times to hold a movable element in closed position.

The specific embodiment of my fastener includes, as shown in detail in Fig. 8, a body plate 10, a rotatable keeper' member 11., which is attached to the body plate by a screw 12, and a leaf spring 13, which is interposed between the keeper member and the body plate and serves to hold the keeper member in either open or closed position.

The body plate, keeper and leaf spring are all preferably formed of brass, although some other metal may be employed if found desirable.

rlhe body plate 10 is preferably, although not necessarily, substantially circular in shape, and is provided with a central opening 14 for the reception of a screw or some other fastening device used in securing the body plate to the structure to which the fastener is applied. On the periphery of the plate 10 there is formed a laterally extending ear 15 which is provided with the threaded opening or orifice, indicated at 16. This opening 1G receives the screw 12 which, by insertion through the openings 17 and 18 of the keeper and spring respectively serves to hold the three elements of the fastener in operative assembled relation.

rlhe leaf spring 13 is substantially l.- shaped in conformation, including a short leg 19 and a long leg Q0. `When the device is assembled, the short leg 19 is engaged against the face of the body plate 10, while the long leg 20 is arranged on the ear 15 to bring the opening 18 of the spring into registration with the threaded opening 16. On the upper face of the long arm 2O of the leaf spring is formed a conical stud, indicated at 21. rl'his stud 21 is adapted to engage in a recess formed in the under face of the keeper 11, as shown particularly in Fig. 2. `When the stud 21 is engaged in this recess it serves to yieldably hold the keeper against rotation. rlhe keeper 11 is substantially rectangular in shape and is cut-away on its under face and at the rear terminal thereof, as indicated at 22. lt is in this cut-away portion 22 that the recess receiving the stud 21 is formed.

The opening 17 of the keeper is preferably of such size that a collar, indicated at 23, may be inserted to insure the free rotatio-n of the keeper on the screw 12. rllhe side edges of the cut-away portion 22 are preferably rounded so that, when the keeper is rotated to move it from open to closed position, the stud will engage an inclined surface, thus facilitating the closing of the keeper. 1t will be obvious upon reference to Fig. 2 particularly that the stud 21 is formed by stamping the metal of the spring 13 upwardly.

"When the keeper is applied to a fountain brush, for which purpose it has been particularly designed, the plate 10 is mounted on the inlet tube 24 of the brush and is brought into engagement with the terminal of the brush handle, indicated at 25. The ear 15 of the plate 10 engages the outer face of the handle, and the keeper is thus positioned so that its locking terminal, indicated at 26, may be brought into engagement with the rear end of the brush and held in this position by the stud 21. 1t is, of course, necessary to form a recess, indicated at 27, in the handle so that, when the keeper is rotated to move it into open position, the rear terminal of the spring 13 may be depressed to release the stud from engagement with the keeper. Obviously, when the keeper has been rotated to move it into open position, it will be held against return movement by the engagement of the stud with the sides of the keeper, unless the return movement of the keeper to closed position is intentional, and the operator exerts sufficient pressure to depress the spring and again engage the stud 21 in the recess of the cut-away portion 22.

In the application of the invention shown in Fig. 1, the fasteners are employed in holding a panel of a door in closed position. This panel is preferably a screen section.

1n reduction to practice, it has been found that the form of this invention illustrated in the drawings, and referred to in the above description as the preferred embodiment, is the most eflicient and practical; yet realizing that the conditions concurrent with the adoption of this device will necessarily vary, it is desirable to emphasize the factthat various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of this invention, as defined in the appended claims.

Having thus described my invention, what I claim as new is l. A fastener including a body plate having an opening adapted to receive a fastening device, a laterally extending ear formed on the body plate, said ear being provided with a threaded opening, a screw threaded into the last-mentioned opening, a keeper rotatable on the screw, a substantially L- shaped leaf spring having its one leg interposed between the keeper and the ear and its other leg bearing against the body plate, and a stud fo-rmed in the leaf spring and engageable with the keeper whereby the keeper may be yieldably held in either open or closed position.

2. A fastener including a body plate, a lateral ear formed thereon, said ear having a threaded opening, a screw threaded into the opening, a keeper rotatable on the screw, the one terminal of said keeper projecting, when in closed position, beyond the body plate, the other terminal of the keeper projecting beyond the free end of the ear, the last-mentioned terminal of the keeper being cut-away on its lower face and having a recess formed in the cut-away portion, a substantially L-shaped leaf spring having its one leg interposed between the keeper and the ear and its other leg bearing against the body plate, and a stud formed on the leaf spring and engageable in the recess of the keeper for holding the keeper in closed position, said stud being adapted to yieldably hold the keeper in open position by engagement with the side edges of the keeper.

3. A fastener including a body plate having a lateral ear provided with a threaded opening, a screw passing through the opening, a keeper rotatable on the screw, a substantially L-shaped leaf spring having one leg interposed between the keeper and the ear, said leg being provided with a stud which is engageable with the keeper for holding the same against rotation, said leg also having an opening receiving the screw, the other leg of the spring being engaged fiatly against the body plate whereby the spring is held against rotation on the screw.

ll. A fastener including a body plate having a lateral ear provided with a threaded opening, a screw passing through the opening, a keeper mounted for rotation on the screw, a leaf spring having an opening receiving the screw, said spring being interpos'ed between the keeper and the said ear, a stud formed on the terminal of the spring and arranged for engagement with the adjacent face of the keeper whereby the same is yieldably held against rotation, and means formed integral with the spring and engaging against the body plate for holding the spring against rotation on the screw.
